Image processing device, image processing method, program, and storage medium

Abstract

In order to enable learning of identifiers for identifying the presence of a target cell in an image while a user performs cell-examination work, an image-feature-value calculation unit (18) extracts image feature values of images of cell-candidate regions. An NRBC identification unit (20) uses previously learned identifiers to identify, on the basis of the image feature values of the images of the cell-candidate regions, whether the target cell is depicted in the cell-candidate regions. It cases when it is identified that the target cell is depicted in a cell-candidate region, an identification-result display unit (26) displays the image of the cell-candidate region. Furthermore, in cases when it is identified that the target cell is depicted in the cell-candidate region, an identifier learning unit (34) performs, on the basis of a user input related to whether the target cell is depicted in the cell-candidate region, identifier learning in which the image feature value of the image of the cell-candidate region is used as a learning sample.

Description

technical field [0001] The present invention relates to an image processing device, an image processing method, a program, and a storage medium. Background technique [0002] When a prenatal fetus is diagnosed, a very small number of fetal-derived nucleated red blood cells (NRBC, hereinafter referred to as target cells) contained in maternal blood is detected and used. Visual detection of NRBCs is a laborious process due to the extremely small number of NRBCs present in maternal blood. Therefore, as described in Patent Document 1, a technique has been proposed in which cells satisfying conditions such as the color, shape, positional relationship, and area ratio of NRBC are searched for from a target image, thereby mechanically detecting NRBC.
